Why doesnt mercury fall into the sun Many say it is due to gravity But gravity between what?

Answer 1

the ansewer is not gravity. Gravity is what keeps it around the sun. you see Mercury has linear motion, which just means it is going strait. if the sun had no gravity mercury would simply fly past the sun and out of the solar system. Also if mercury had no linar motion it would simply fall strait into the sun. so.. it is the balance of gravity with mercury's linear motion that keeps it in orbit around the sun.

Answer 2

Mercury orbits the Sun because of the balance between the pull of the Sun's gravity and the inertia of Mercury's motion. Gravity is the force of attraction between any two objects with mass, in this case, between the Sun and Mercury. The gravitational force between the Sun and Mercury keeps Mercury in its orbit instead of falling into the Sun.
